+// float log1pf(float)
+//
+// log1p(x) = log(x+1)
+//
+// Overview of operation
+//==============================================================
+// Background
+// ----------
+//
+// This algorithm is based on fact that
+// log1p(x) = log(1+x) and
+// log(a b) = log(a) + log(b).
+// In our case we have 1+x = 2^N f, where 1 <= f < 2.
+// So
+//   log(1+x) = log(2^N f) = log(2^N) + log(f) = n*log(2) + log(f)
+//
+// To calculate log(f) we do following
+//   log(f) = log(f * frcpa(f) / frcpa(f)) =
+//          = log(f * frcpa(f)) + log(1/frcpa(f))
+//
+// According to definition of IA-64's frcpa instruction it's a
+// floating point that approximates 1/f using a lookup on the
+// top of 8 bits of the input number's + 1 significand with relative
+// error < 2^(-8.886). So we have following
+//
+// |(1/f - frcpa(f)) / (1/f))| = |1 - f*frcpa(f)| < 1/256
+//
+// and
+//
+// log(f) = log(f * frcpa(f)) + log(1/frcpa(f)) =
+//        = log(1 + r) + T
+//
+// The first value can be computed by polynomial P(r) approximating
+// log(1 + r) on |r| < 1/256 and the second is precomputed tabular
+// value defined by top 8 bit of f.
+//
+// Finally we have that  log(1+x) ~ (N*log(2) + T) + P(r)
+//
+// Note that if input argument is close to 0.0 (in our case it means
+// that |x| < 1/256) we can use just polynomial approximation
+// because 1+x = 2^0 * f = f = 1 + r and
+// log(1+x) = log(1 + r) ~ P(r)
+//
+//
+// Implementation
+// --------------
+//
+// 1. |x| >= 2^(-8), and x > -1
+//   InvX = frcpa(x+1)
+//   r = InvX*(x+1) - 1
+//   P(r) = r*((1 - A2*4) + r^2*(A3 - A4*r)) = r*P2(r),
+//   A4,A3,A2 are created with setf instruction.
+//   We use Taylor series and so A4 = 1/4, A3 = 1/3,
+//   A2 = 1/2 rounded to double.
+//
+//   N = float(n) where n is true unbiased exponent of x
+//
+//   T is tabular value of log(1/frcpa(x)) calculated in quad precision
+//   and rounded to double.  To load T we get bits from 55 to 62 of register
+//   format significand as index and calculate address
+//     ad_T = table_base_addr + 8 * index
+//
+//   L1 (log(2)) is calculated in quad precision and rounded to double;
+//   it's created with setf
+//
+//   And final result = P2(r)*r + (T + N*L1)
+//
+//
+// 2. 2^(-40) <= |x| < 2^(-8)
+//   r = x
+//   P(r) = r*((1 - A2*4) + r^2*(A3 - A4*r)) = r*P2(r),
+//   A4,A3,A2 are the same as in case |x| >= 1/256
+//
+//   And final result = P2(r)*r
+//
+// 3. 0 < |x| < 2^(-40)
+//   Although log1p(x) is basically x, we would like to preserve the inexactness
+//   nature as well as consistent behavior under different rounding modes.
+//   We can do this by computing the result as
+//
+//     log1p(x) = x - x*x
+//
+//
+//    Note: NaT, any NaNs, +/-INF, +/-0, negatives and unnormalized numbers are
+//          filtered and processed on special branches.
+//
